Clarion University physics professor Dr. Chunfei Li will present “Electron Microscopy: A Brief Introduction” from 11 to 11:45 a.m. Oct. 14 in Grunenwald Center for Science and Technology, room 122.
Li will discuss how an electron microscope works, the strengths and weaknesses of an electron microscope and what Clarion's scanning electron microscope can do. Those attending can view the microscope and experience how it functions.
The state-of-the-art, research-grade scanning electron microscope, purchased in 2013 through an National Science Foundation grant, allows students to observe subjects at the nanometer level. For perspective, the diameter of a human hair is 100 micrometers, and a micrometer is 1,000 nanometers. It is rare, even at the national level, for a teaching university to have this level of instrumentation.
Li's talk is part of Western Pennsylvania American Association of Physics Teachers' meeting. It is free and open to the public.
